The passive flux meter (PFM) enables the measurement of cumulative water and contaminant mass fluxes in porous aquifers. It consists of a sorbent material, which is installed in a monitoring well to intercept groundwater flow. Tracer losses and contaminant retention on the sorbent are used to estimate water and contaminant mass fluxes through the device. In the multi-layer PFM different (sorbent) materials are used in an annulus (layer-type) configuration. This allows leached tracers inside thedoi:10.2495/afm120271 fatcat:fq777xgcuvacbbvf6x5euped3e
